"Old Testament saints slept in the grave. For, before the resurrection of Christ there was no prepared spiritual immortal body for anyone to put on at death. However, after the Parousia the soul no longer sleeps in death. Sleep was applied to all the dead that anticipated the Parousia or arrival of Christ in the first century. After A.D. 70, no one is asleep in the graves. For those who die now, put on the "house which is from heaven" at death.
We are now in the Parousia and when we put off the body that came from the ground, we put on the body that comes from heaven. We have our new immortal bodies which are put on at this death and resurrection."
"I believe that after the resurrection and parousia at the close of the dispensational age in A.D. 70, everyone in Christ who dies put off the old fleshly body and put on the new spiritual body that God has prepared for them."
